![]() ![]() You can find the export value by examining the normal appearance keys are set to the export value and /Off. The latter two has to do with appearance in interacting with the mouse, the normal appearance has to do with how the form is printed. Each annotation has up to 3 appearances in it's appearance dictionary /N, /R and /D, standing for normal, rollover, and down (§12.5.5). If you do not have acrobat and can not find the export value, you can discover it by looking at appearance dictionary /AP and specifically at the /N field. ![]() In that case, while the code does work, we feel the the best solution is to delete the /V as well as the /ASfield from the dictionary. If you are using the form not only for automatic filling but also for manual filling you may wish the box to be checked as a default. You will see that the /V and /AS fields are set to the export value not Yes. However, you may not have the luxury and upon closer inspection of a form where the export value is not set to Yes. In fact the recommendation in the specification is that it be set to Yes. The easiest solution if you designed the form or can use acrobat to edit the form is to ensure that the export value of the checkbox is Yes and the default state of the box is unchecked. This will work especially when the export value of the checkbox is Yes, but doesn't need to be. BasePdfName ( '/Yes' ) else : val_str = pdfrw. If we were to run the first code block to examine the annotations, we get the following:ĭef checkbox ( annotation, value ): if value : val_str = pdfrw. Once in the information block at the top where name and address information is filled out, but also at the bottom in the signature block. This form differs from sample_form1.pdf only in that the Name field appears twice. write ( out_path, pdf ) Multiple Fields with Same Nameįor text fields: Simple? Well not quite. to_unicode () if key in data : pdfstr = pdfrw. pages : annotations = page if annotations is None : continue for annotation in annotations : if annotation = '/Widget' : key = annotation. If you search the internet, including the above mentioned Medium blog post, you will find a snippet of code which might look like the following:ĭef form_filler ( in_path, data, out_path ): pdf = pdfrw. Finding Your Way Around PDFrw and fillable forms Finally, we'll offer a solution for consolidating multiple filled forms into a single PDF while preserving the filled forms (and maintain editability). ![]() We will then look at checkboxes, radio buttons, combo boxes and lists. We will first look at text form fields and discuss how to access fields that are repeated. We will cover the basics of using PDFrw to explore fillable forms and look at basic data types within PDFrw. The forms are confirmed to work with Acrobat Reader, but not tested across the board with different readers. The scope of this series applies to PDF 1.7 at this time no investigation as to whether techniques apply to PDF 2.0 or forms designed with Adobe LifeCycle. Another useful resource is the PDF 1.7 specification, but it is well over 750 pages!. The blog post is long on python practices and a bit short on PDF details. No single source provides a complete answer, however, this blog post in Medium by Vivsvaan Sharma is a good starting place. Bits and pieces can be found throughout the Internet and places like Stack Overflow. Programatically filling in PDF forms can be a quick and accurate way to disseminate forms. Furthermore, to make life easier for the staff, PDF forms for multiple patients needed to be consolidated into a single PDF. To meet the challenges, PDF forms have repeated fields with same name, checkboxes and radio buttons are used. While the idea of using pre-populated fillable PDF forms is a simple one, implementation is full of challenges as many common programmatic PDF tools do not properly work with filled forms. Quite a lot of data is repeatedly asked for to make appointments, on consent forms and in reminder cards. With the goal of providing a senior friendly vaccine experience, Gary and Mary West PACE which stood up a small senior oriented covid vaccine clinic desires to mitigate the amount of paperwork a frail senior is subjected to.
